update(bump-basic): highcharts — comprehensive quality review (#4338)

## Summary

Updated **highcharts** implementation for **bump-basic**.

### Changes
- More varied rankings (no perfectly static teams — Sharks/Lions now
swap positions)
- Adjusted margins (marginRight 250→480) for end labels visibility
- Added marginTop for better title spacing
- Quality self-assessment: 93/100

## Test Plan

- [x] Preview images uploaded to GCS staging
- [x] Implementation file passes ruff format/check
- [x] Metadata YAML updated with current versions
- [ ] Automated review triggered
